Android studio之廣播監聽接收短信

一． 在清單文件中（AndroidManifest.xml）添加短信權限

這里我用的android studio版本是3.3的

 

<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.SEND_SMS" />

二．3.2以上的android studio可直接新建廣播SMSReceiver類

注意（這里新建的廣播類，它默認為靜態廣播，所以在清單文件會自動生成以下代碼）

<!-- <receiver -->
<!-- android:name=".SMSReceiver" -->
<!-- android:enabled="true" -->
<!-- android:exported="true"> -->
<!-- <intent-filter android:priority="20"> -->
<!-- <action android:name="android.provider.Telephony.SMS_RECEIVED"/> -->
<!-- </intent-filter> -->
<!-- </receiver> -->

我用的是動態注冊廣播，這里注釋掉

 直接上廣播類SMSReceiver的代碼public String msgBody="";

 public String originatingAddress="";

 Context context;
 public SMSReceiver(Context context){
     this.context=context;
 }
 @Override
 public void onReceive(Context context, Intent intent) {
     String action =  intent.getAction();
     if(action.equals("android.provider.Telephony.SMS_RECEIVED")) {
         //獲取短信內容,有可能一次發來多條短信
         Object[] objects = (Object[]) intent.getExtras().get("pdus");
         for (Object obj : objects) {
             //獲取短信對象
             SmsMessage msg = SmsMessage.createFromPdu((byte[]) obj);
             //獲取短信內容
             msgBody = msg.getDisplayMessageBody();
             //獲取發信人的電話號碼
             originatingAddress = msg.getOriginatingAddress();
             Log.i("wk", "短信內容==>" + msgBody + " 來自==>" + originatingAddress);
             Toast.makeText(context,"短信內容==>" + msgBody + " 來自==>" + originatingAddress,Toast.LENGTH_SHORT).show();
         }
     }
 }

 

三．  注冊動態廣播，並申請系統短信權限

SMSReceiver smsReceiver=new SMSReceiver(SMSActivity.this);

//動態注冊廣播

IntentFilter intentFilter = new IntentFilter();
 intentFilter.addAction("android.provider.Telephony.SMS_RECEIVED");
 registerReceiver(smsReceiver,intentFilter);

/**
  * * 檢查申請短信權限
  * */
 private void checkSMSPermission() {
     if (ContextCompat.checkSelfPermission(this, Manifest.permission.READ_SMS)  != PackageManager.PERMISSION_GRANTED) {
         //未獲取到讀取短信權限
         Toast.makeText(this,"未獲取權限",Toast.LENGTH_SHORT).show();
         // 向系統申請權限
         ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.READ_SMS}, REQ_CODE_CONTACT);
     } else
         {
             query();
         }
 }

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {

    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    //判斷用戶是否，同意 獲取短信授權
    if (requestCode == REQ_CODE_CONTACT && grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
        //獲取到讀取短信權限
        query();
    } else {
        Toast.makeText(this, "未獲取到短信權限", Toast.LENGTH_SHORT).show();
    }

}

//根據之前在廣播類公有屬性短信內容和短信來源，在activity界面可以直接獲取，並讀取顯示

//顯示最近一條信息
 private void dispLast(){
        String msg=smsReceiver.msgBody;
        String originatingAddress=smsReceiver.originatingAddress;
       edit_sms.setText("短信內容==>" + msg + " 來自==>" + originatingAddress);
 }
